ABSTRACT:
Two robotic arms roam in separate, non-overlapping areas of a test station, avoiding collisions. A traveling buffer moves along x-tracks between a front position and a back position. In the front position, a first robotic arm loads IC chips from an input tray or stacker into buffer cavities in the traveling buffer. The traveling buffer then moves along the x-tracks to the back position, where a second robotic arm moves chips from the traveling buffer to test boards for testing. After testing, the second robotic arm moves chips to a second traveling buffer, which then moves along tracks to a front position for unloading by the first robotic arm. Two traveling buffers may move on the same tracks in a loop. The buffer cavities in the traveling buffer move on internal tracks to expand and contract spacing and pitch between the front and back positions to match test-board pitch.
